If you call John Boyd for
your seasonal maintenance, your technician will
change your heating and cooling filters as part
of the visit. But that doesnít mean you can
ignore them in between! Filters may need to be
changed as often as every month, depending on
the type of filters you use.

Standard filters are made
of fiberglass and rimmed with light cardboard.
These filters are designed to capture the
particles necessary to keep your equipment clean
and running efficiently, not to clean the air.
Standard filters should be changed monthly while
heating or cooling equipment is in use.

If you want to filter the
air thatís running through your equipment for
increased air quality, youíll need higher
efficiency filters designed to trap smaller
particles like dust and pet dander. High
efficiency filters should be changed every three
months.

Another option would be
permanent filters, which use a slight
electrostatic charge to attract airborne
particles, and which may also include activated
charcoal to reduce odors. These filters are not
replaced, but must be washed regularly.

Ask one of our technicians
where your filters are and how to change them,
plus which filter types would be best for your
home.
